英文摘要	The Institute of Atmospheric Sciences of the South Dakota School of Mines and Technology has completed 20 months of ambient air sampling at rural and remote sites in a five-state region of the northern Great Plains. Sampling was accomplished by use of a 27-ft motor home laboratory containing living accommodations for a field crew of two. The laboratory was outfitted with a number of instruments for measurement of pollutant parameters: cloud condensation nuclei, ice nuclei, Aitken nuclei, size distribution information for Aitken size particulate, sulfur dioxide, ozone, raindrop size distributions, and pH of precipitation. In addition, an instrumented meteorological tower provided wind speed, wind direction, ambient air temperature, and dew-point temperature. Instruments varied as to durability and success of operation, but better than 90% data retrieval was possible for the entire 20-month sampling study. Analyses of the large quantities of data obtained were not possible under the initial baseline measurement program, but examination of most parameters indicate that the air masses in the northern Great Plains are still relatively clean and are influenced primarily by local sources of contamination rather than large regional sources. Particulate concentrations in these remote areas are representative of mountain stations or clean rural conditions, and sulfur dioxide concentrations are at the threshold of detectability of the instrument. Precipitation is only very slightly acidic, and no significant quantity of amorphous particles (such as coal dust or combustion products) is found in the quantitative analyses of the high-volume filter collections. A summary of ''average'' conditions observed over the study area is tabulated.
